Hi guys, so far I only found 1 EastAsia 9800 OS by Rogers.9800jAsia_PBr6.0.0_rel695_PL6.4.0.105_A6.0.0.246_R ogers_Wireless_Inc.exe
I'm not really satisfied by its performance, especially there's a huge signal strength difference with my previous 9700.

Is it possible for us to use a latest Multilanguage version (9800M PBr6.0.0_rel862 PL6.4.0.120 A6.0.0.284_Bouygues) and add in CJK read and write font support manually, as mentioned by our mate here?
Is there any impact or side-effect by doing that?
